Randall Hydraulics -
These high performance piston units are part of the Parker Mobile Products range. Previously marketed under the Volvo and VOAC names they continue to be manufactured in Sweden at the former Volvo Hydraulics plant.
Some of the original F11 line has been superseded by the later F12 range, and new F11 and variable displacement V14 motors are now in production.
Features of VOAC - Bent-Axis Pumps & Motors
- High axis angle reduces envelope size and improves efficiency
- Spherical piston design allows very high motor speeds
- Laminated piston ring minmises leakage
- F11/F12 displacements from 5 cc to 250 cc/rev
- V12/V14 displacements from 60 to 160 cc/rev
- Continuous pressure rating 350 bar for F11 and 420 bar for F12/V12/V14
- Peak pressure rating 420 bar for F11 and 480 bar for F12V12/V14
Options of VOAC - Bent-Axis Pumps & Motors
- Metric or imperial keyed or splined shaft (most models)
- CETOP or SAE mount for F11
- ISO, SAE or Cartridge mount for F12/V12/V14
- Low noise and handed port plates for pump variants of F11/F12
- Speed pickup
- Valve assemblies for braking, cross-line relief and hot oil purge/flushing with F12/V12/V14
Applications of VOAC - Bent-Axis Pumps & Motors
- Construction/mining equipment
- Drilling equipment
- Agricultural machinery
- Forestry equipment
- Submersible pumps
